A garden saw is a tool designed for cutting branches and small trees in a garden or yard. It typically features a long, serrated blade that allows for efficient cutting through wood. Garden saws come in various types, including hand saws and powered saws, making them versatile for different gardening tasks. These saws are essential for maintaining healthy plants by allowing gardeners to prune overgrown branches and remove dead wood. Using a garden saw helps promote better air circulation and sunlight exposure for the remaining plants, contributing to a healthier garden overall.
